COMPETENCY-BASED QUESTIONS
1. Aarush connects a metal and a plastic spoon to a battery and a bulb to test his
circuit. The bulb glows when he uses the metal spoon but does not glow with the
plastic one. Why does the bulb glow only with the metal spoon?
2. Riya notices that at home, each light and fan can work even if one switch is off.
She wonders how that happens. What type of circuit is used in Riya’s house?
Make two circuits using the components — one in a line for a series connection and another
with separate paths for a parallel connection. Watch how the bulbs glow in each circuit
and notice the difference in their brightness.
